Operation
Note:
Determine the left and right sides of the
machine from the normal operating position.
CAUTION
If you leave the key in the ignition switch,
someone could accidently start the engine
and seriously injure you or other bystanders.
Remove the key from the ignition before you
do any maintenance.
Adjusting the Height of Cut
The height of cut is adjustable from 25 to 152 mm (1
to 6 inches) in 13 mm (1/2 inch) increments. To adjust
the height of cut:
1.
Park the machine on a level surface, raise the
cutting unit to the T
RANSPORT
position, engage
the parking brake, shut off the engine, and
remove the key.
2.
Perform the following procedures:
•
Position the castor wheel axles in the upper
or lower holes of the castor forks; refer to
Positioning the Castor-Wheel Axles (page
12)
.
•
Add or remove an equal number of spacers
from the castor forks; refer to
Castor-Fork Spacers (page 12)
.
•
Use the pins in height-of-cut plates to position
the lift-arm chains; refer to
Height-of-Cut Chain (page 13)
.
Positioning the Castor-Wheel
Axles
Position the castor-wheel axles in the same holes in
both castor forks. Refer to
and
to
determine the correct holes for the setting.

Note:
If you operate with a 64 mm (2-1/2 inch) height
of cut or higher, set the axle bolt in the lower hole to
prevent grass buildup. If you detect grass buildup
while operating, reverse the machine direction to pull
any clippings away from the wheel/fork area.
Positioning the Castor-Fork
Spacers
1.
Remove the tensioning cap from the spindle
shaft (
) and slide the spindle out of the
castor arm. Put the 2 shims onto the spindle
shaft as they were originally installed. These
shims are required to achieve a level across the
entire width of the cutting units.
2.
Slide the appropriate number of spacers onto
the spindle shaft to get the desired height of cut
(
).
